Abstract

There is a need for an improved understanding of rate effects over a wide range of strain rates in order to improve the modelling and analysis of high strain rate activities. Using triaxial testing on reconstituted kaolin over a wide strain rate range this paper examines the impact of strain rate on the aspects of soil response which are important in many areas of geotechnical engineering. It is demonstrated that shear strength, small strain stiffness and the elastic shear strain threshold are rate dependent.
